(A) Water wells shall be so located that there will be no danger of pollution from flooding or from unsanitary surroundings, such as privies, sewage, sewage treatment plants, livestock and animal pens, solid waste disposal sites, underground fuel storage tanks, or abandoned and improperly sealed wells.
(B) No well site which is within 50 feet of a tile or concrete sanitary sewer, or storm sewer, or which is within 150 feet of a sewerage appurtenance, septic tank, septic tank perforated drain field, absorption bed, evapotranspiration bed or underground fuel storage tank will be acceptable for the development of the water well. Sanitary or storm sewer constructed of ductile iron or polyvinyl chloride (PVC) pipe meeting American Water Works Association (AWWA) standards, having a minimum working pressure of 150 pounds per square inch (psi) or greater, and equipped with pressure-type joints may be located at distances of less than 50 feet from a proposed well site, but in no case shall the distance be less than ten feet.
(C) No well site shall be selected which is within 500 feet of a sewage treatment plant or within 300 feet of a sewage wet well, sewage pumping station, or a drainage ditch which contains industrial waste discharges or the wastes from sewage treatment works.
(D) No water well shall be located within 500 feet of animal feedlots, solid waste disposal sites, lands on which sewage plant or septic tank sludge is applied, or lands irrigated by sewage plant effluent.
(E) No water well shall be located within 1,500 feet of a city public water well, and shall pose no threat to the continued production of the city well.
(F) Livestock in pastures will not be allowed within 50 feet of the water well.
(G) Wellheads and pump bases shall be sealed by a gasket or sealing compound and properly vented to prevent the possibility of contaminating the well water. A well-casing vent shall be provided with an opening that is covered with size 16 mesh or finer corrosion-resistant screen, facing downward, elevated and located so as to minimize the drawing of contaminants into the well. Wellheads and well vents shall be at least two feet above the highest known watermark or 100-year flood elevation, if available, or adequately protected from possible flood damage by levees.
(H) Sanitary control easements covering land within 150 feet of the well are required. The sanitary control easement secured shall provide that none of the pollution hazards, or any facilities that might create a danger of pollution to the water to be produced from the well, will be located thereon. For the purpose of a sanitary control easement, an improperly constructed water well is one which fails to meet the surface and subsurface construction standards for public water supply wells. Residential type wells within a sanitary control easement must be constructed to public water well standards. A copy of the recorded sanitary control easement shall be included with plans and specifications submitted to the Public Works Director for review. With the approval of the Public Works Director, the applicant may submit any of the following as a substitute for obtaining, recording, and submitting a copy of the recorded sanitary control easement covering land within 150 feet of the well:
(1) A copy of the recorded deed and map demonstrating that the applicant owns all real property within 150 feet of the well.
(2) A copy of the recorded deed and map demonstrating that the applicant owns a portion of real property within 150 feet of the well, and a copy of the sanitary control easement that the applicant has, obtained, recorded, and submitted to the Public Works Director applicable to the remaining portion of real property within 150 feet of the well not owned by the applicant.
(3) For a political subdivision, a copy of an ordinance or land use restriction adopted and enforced by the political subdivision which provides an equivalent or higher level of sanitary protection to the well as a sanitary control easement. Any lines crossing under or across a city easement, street, or right-of-way must be submitted on plans from a licensed professional engineer and will meet the construction standards approved by the Public Works Director for the city.
